Body
In the llvm tutorials and examples, the compiler outputs LLVM IR by making calls like this <pre><code>return Builder.CreateAdd(L, R, "addtmp"); </code></pre> but many interpreters are written like this: <pre><code>switch (opcode) { case ADD: result = L + R; break; ... </code></pre> How would you extract each of these code snippets to make a JIT with LLVM without having to re-implement each opcode in LLVM IR?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
